Chitsulo Chosapanga Chitsulo Chopanda Msoko cha S32750 Chithunzi Chodziwika
  • Chitsulo Chosapanga Dzimbiri Chopanda Msoko cha S32750 1

Machubu Opanda Zitsulo Zosapanga Chitsulo cha S32750

Kufotokozera Kwachidule:

Alloy 2507, yokhala ndi nambala ya UNS S32750, ndi alloy ya magawo awiri yochokera ku dongosolo la iron-chromium-nickel yokhala ndi kapangidwe kosakanikirana ka austenite ndi ferrite mofanana. Chifukwa cha duplex phase balance, Alloy 2507 imatsutsa bwino dzimbiri monga momwe zitsulo zosapanga dzimbiri za austenitic zokhala ndi zinthu zofanana zophatikizira. Kupatula apo, ili ndi mphamvu zambiri zomangirira komanso zokolola komanso kukana bwino kwambiri kwa chloride SCC kuposa a austenitic pomwe imasunga kulimba bwino kuposa a ferritic.

Chiyambi cha Zamalonda

Super Duplex yosapanga dzimbiri ngati S32750, ndi kapangidwe kakang'ono kosakanikirana ka austenite ndi ferrite (50/50) komwe kwakhala ndi mphamvu kuposa chitsulo cha ferritic ndi austenitic. Kusiyana kwakukulu ndikuti Super Duplex ili ndi kuchuluka kwa molybdenum ndi chromium komwe kumapereka zinthuzo zambiri. Chromium yapamwamba imalimbikitsanso kupanga magawo owononga a intermetallic, omwe amakhudzidwa ndi 475°C embrittle chifukwa cha mvula ya gawo la α' lolemera chromium, komanso embrittle ndi sigma, chi ndi magawo ena kutentha kwambiri.

Alloy 2507 (S32750) ilinso ndi nayitrogeni wambiri, zomwe sizimangolimbikitsa kupanga austenite ndikuwonjezera mphamvu, komanso zimachedwetsa kupanga magawo apakati pazitsulo kuti zilole kuti ntchito yokonza ndi kupanga duplex grade ichitike.

Mtunduwu umadziwika ndi kukana dzimbiri kwa chloride bwino kwambiri, kuphatikiza ndi mphamvu zambiri zamakaniko. Ndi woyenera kugwiritsidwa ntchito m'malo ouma monga madzi otentha a m'nyanja okhala ndi chlorine komanso zinthu zokhala ndi asidi.

Makhalidwe a Alloy 2507 (S32750) ndi awa:

● Kukana bwino kwambiri kupsinjika kwa dzimbiri (SCC) m'malo okhala ndi chloride
● Kulimbana bwino ndi dzimbiri la dzenje ndi ming'alu
● Kukana kwambiri dzimbiri lonse
● Mphamvu kwambiri yamakina
● Kapangidwe ka zinthu zakuthupi komwe kamapereka ubwino wopangira
● Kulimba kwambiri ku dzimbiri ndi kutopa kwa dzimbiri
● Kutha kupotoka bwino

S32750 yapangidwa kuti igwiritsidwe ntchito molimbika kwambiri komanso molimba mtima, zomwe zimapezeka munjira ya mankhwala, zida za petrochemical, ndi madzi a m'nyanja. Zimagwiritsidwa ntchito kwambiri pofufuza/kupanga mafuta ndi gasi m'mphepete mwa nyanja komanso m'makina osinthira kutentha pokonza petrochemical/mankhwala. Kapangidwe kake ndi koyeneranso kugwiritsidwa ntchito ndi ma hydraulic ndi zida m'malo otentha a m'nyanja.
